FRANK C. RINsCHE, or DETROIT, MICHIGAN, AssIGNoR To BURHoUGHs ADDINGMACHINE COMPANY, or DETROIT, MICHIGAN, A CORPORATION or MICHIGAN.

T0 all whom t may concern:

Be it known that I, FRANK C. I INsoHE, a y citizen of the United States,residing at Detroit, in the county of Wayne andState of Michigan, haveinvented certain new land .llseful Improvements in Adding-Machines,

of which the following is a specification.

This invention relates more especially to 0f machine and has special reerence to laterally shiftable paper carriage with suitable means lforsetting the same at different columnar positions and for effectingautomatic line-spacing in whatever position the carriage may be located.

The object of my present invention is to,

better adapt the tabulating equipment Otan adding and listing machine tothe handling Aof sheet paper of stronger texture or greater thickness orstiffness than ordinary letter paper, such for example as now commonlyused' for ledger sheets in connection with looseleaf systems ofbookkeeping. The ordinary roller platen such as employed quite generallyin adding and listing machines, has been found to be objectionable, ashave also the customary arrangements for feeding sheets in from the rearof the paper carriage,V

on account of the degree of bending of the sheets, whose texture issuchthat the bend It is obviously desirable that the iatness of the sheetsshall be preserved so that when they emerge from the machine theiradaptability for handling in the. customary way as loose leaves shallnot have been impaired. In carrying out my invention I provide for soholding sheets, of paper in the laterally shiftable carriage as to avoidall necessity for bending or curling to a degree which will permanentlyaffect the flatness of the sheet, while -at the same time I provide forpresenting the sheet to the type. With sufiicient conveXity to insure gclean printing.

For prior tabulating equipments `applied to Burroughs adding'machinesreference may be had to the following patents: No. 595,864,

J une 3, 1913. All of these patents show laterally shiftable papercarriages ,with roller', 1'

platens around which the paper, eitherl in sheets or in strip' formdrawn from a roll, is adapted ytopass, being introducedirom the rearinto the bite between theroller platen and `pressure feed rollers 4,andthence being.4

guided over the surface/of the roller platen and emerging over Jthe topthereof or vertically from the ,frrnt side of the platen. In

my prior application filed February 21, 1914, Serial.No.820,127, thereis shown a form of paper, holder specially designed for the handling ofledger sheets and the like, this holder having a high back against whichthe sheet can rest in flat form, but this holder is nota platen andthere is employedin conf nection with it the familiar' roller platendown behind which the sheets are fed so that .they must, as in othercases, bend or curl fully half way around. the rollerk platen,

`which is of relatively small diameter.

According to my present invention I do away altogether with the rollerplaten and employ a holder for the sheets, which holder itselfconstitutes a. platen. holder and platen is in the form of a segnient ofa cylinder and is so mounted at the rear of the machine that a sheet ofpaper held upon it may be presented to the type much as paper hasheretofore been presented This `combined Y manner' of feeding of paperpast to the type while overlying a roller platen, in that there is aconvexity with relation to the type which though not anywhere near aspronounced as that incident to the use of a roller platen isnevertheless sufficient to insure clean printing, particularly whenemployed in connection with segmental typecarriers such as commonlyfound in Burroughs adding machines. Referring to Fig. l, referencenumeral G11 designates the far miliar type-carrying levers'of aBurroughs machine, which levers have segmental rear portions carryingsegmental series of types 618. The reference numeral 2 designates theplaten of my invention whose convex relationship to the type is clearlyportrayed 1n Fig. l. This platen is arranged to work up and down insuitable guides supplied by a frame structure mounted to rock forwardand backward somewhat as does the familiar cradle of the prior'constructions, in which the roller platen is carried. .It will beunderstood that the sheet of paper lies over this platen backed upthroughout thereby` and that there is no feeding of the paper beyond theplaten as work proceeds after the a roller platen. In consequence theplaten of my vpresent invention is required to have a considerable rangeof vertical movement and lcorres'pondingly the frame `structure whichsupplies the guides must' haveA considerable vertical extent making itquite a different affair from the familiar roller platen cradle and alsocalling for a .difference in the mounting of this cradle upon thelaterally lshifting carriage. In fact some modification is requiredofthe carriageproper and the track on which it runs in order toaccommodate these parts to the new type of platen which is the subjectof this application.

Thus the track 3 is located much lower down -on the back of themachinethan such tracks as shown in the above-mentioned patents and infact so low down that its lower portionoverhangs the base of the machineso that I nd it expedient to put upon this track-casting the hinge lugs3a such as commonly found upon the back panel of the machine, theselugs,tting between the usual lugs upon the base. The track casting is soformed that when fastened ragainst the back of the machine its upper andlower ball-- bearing grooves will be in a plane at an angle to thevertical with the upper part of the track forward so that the carriagewill have a corresponding forward tilt and the platen guide frame orcradle may be -mounted at its lower end in side brackets of the carriageso as to most effectively correlate the platen to the type having regardto the desired convexity at the printing line. The carriage proper isdesignated by the numeral 4 and the side brackets by the numeral 4, itbeing noted that these brackets ing have an increased angularity overthat of the carriage proper, besides which the `bosses mental sidepieces are rigidly united by' crossing v arms or webs L5b and ahorizontal web 5, Fig. 2. When the cradle is rocked forward lugs 5d onthe side pieces 5 abut. 'l against the' heads of bolts 6 which-screw yinto ears 4d of the carriage brackets and are locked by nuts 6a, (Fig.1).l Obviously these i abutment bolts provide for adjustment in 'p theinterest of securin just the right amount of forward swing of t e platento best position it forreceiving type impressions..

The platen 2 comprises a metal plate faced with rubber. Angle strips orbars 7 'and 8 are secured yacross the back of the metal plate at the topand bottom, serving to stiften the same and functioning otherwise aswill presentlybe pointed out. Segmental racks 9 are secured to the-backof the plate along the' sides thereof andv serve to further stiffen it,besides constitutmedia through which line spacing movements are impartedto the platen. These alo' racks have laterally-projecting flanges 9a lwhich overlierabbeted portions 5 of the 10o 1 y cradle side pieces 5(Fig. 6). Metal strips 10 secured to the faces of said cradle si epieces complete grooves in which the said rack ilanges are confined forpurposes-of,

platen in its movements 1n al guiding the circular path.

A Referring next nism, a shalt la is journaled in bearings on the cradleside pieces 5, and pinions 15am fastened to this shaft near oppositeends thereof, said pinions meshing with the racks 9 respectively. Saidshaft protrudesat the right where it carries a feed ratchet 16 anddetentwheel 17. 'A pair of arms 18 journaled ,upon the shaft on oppositesides of said' ratchet carry between them a pawl 19, and a link 20connects said arms with a bell crank lever 21 pivoted on a stud 22 whichis Vsecured in a short arm le of the righthand carriage bracket 4a. Alink 23 connects this bell crank lever with a slotted arm 25 fastened toa rock shaft 26 extending from side to side of the carriage andjournaled in the end plates orV brackets thereof. This rock shaftcorresponds with those to be found in the before mentioned patents asparts of linespacing bails and in the present instance constitutes thepivot shaft of a similar bail comprising a cross rod 27 and arms28connecting it with said rock shaft. Owing to the low position of thecarriage in the present in- 101sV to the line-spacing mecha? stance, adirect engagement between this` l between the link 23 and arm 25 to varythe line-space stroke, and itwill be obvious that thev connectionsdescribed provide for step -Y .by ,step turning of the ratchet wheel.This *is'accompanied by step by step turning of l "fthe'pinions 15 in adirection to elevatethe platen. As in Amachines of said prior pat- 'Yents, ythe pawl -19 is normally disengaged gfromthe'ratchetthrougheontact of a curved A finger of the pawl with a stud on which ispivoted the familiar spring-held detent arm 81 lhaving a small rollwhich engages the detent wheel 17. Inl viewof' the weight 'of theplaten,I provide means additional to these usual detent devices, forresisting gravitation. Thus I surround the shaft 14 with a long coiledspring 40 (Fig. 2) which' at one end is secured to a bracket 41 fastenedto a lug on the leftside piece 5 of the cradle, said Vspring beingsecured at` its other end to a notched cup 42 embracing thel hub of therighthand gear wheel 15. The spring' is suitably tensioned and one ofthe notches of Y its cup 42 is engaged with a pin 15a on said hub and itacts in opposition to descent of the laten and with sufficient force tocounteralance the same and insure its standing in any position to whichit ismoved. The printing line/is indicated by markers fastened to thestrips or plates 10 (Fig. 3,) and vthe sheet 4overlying the platen isadjusted to these markers through use of a twirler knob 51 on the end ofthe shaft 14, it bein understood that thebottom edge of every s ieet putin the machine is gaged the same. The printing may begin with theplaten'in any intermediate position but the last imprint which any sheetcan take will 4occur with theplaten in the same position in everyinstance.

most position to which the platen can be moved. Itis desirable todefinitely and positively limit the upward movement of the platen and tothis end I secure to the horizontal cross web 5c an upright arm 52having a forwardly turned abutment flange 52a at its upper end, againstthe under edge i of which flange the lowerl langle bar 8 strikes `whenthe platen reaches the limit of 'its upward, movement. Downward movementof the platen is similarly limited by the striking of the upper` anglebar 7 against the top edge of the flange. The said arm 52 is preferablyreinforced by a bracket 58 Y which extends adjacent assessing of a...

diagonal Webs 5b In order to prevent thefniachine'from bev to rest upon.

This will be the uppercoming locked through blocking of the linespacemechanism when the platen is at the uppermost limit of its movement. Iprovide for automatically disengaging the pawl 19 from the ratchet wheel16 uponv arrival of the platen `at such extreme of movement. To this endI pivot aforked rocker piece 60 to the -ri fhthand side piece of thecradle frame ('Iiigs. 2 and 5), the two branches of this'forked rockerpiece being offset from each other laterally and one arranged to beacted upon by the platen and the other arranged to act yupon the pawl.Thus the forward branch 60a has a cam rise 60b at its upper end againstwhich thev liange of the lower. *angle bar 8 strikes. The rear branch60c has a curved terminal portion 60d extending in front of a pin 19a onthe pawl. When the rocker piece is thrown vrearward through engagementof the angle strip with the cam rise, as illustrated in Fig. 5, the rearbranch disengages the pawl from the ratchet sal so that any 'furtheroperationvof the machine will not cause the pawl to act .against theratchet.

For the purpose sheets against the face of the platen, I employ flexiblesteel bandsv 70 overlying the platen at opposite sides thereof 'asillustrated in Figs. 3 `and .12. These bands are pivotally connected attheir lower ends to a strip or bar y7 1 which extends across the lowermargin of the platen and is itself pivoted `to a rod 72. The latteroccupies a position below and to the rear of the lowe-redge of theplaten andextends from side to side thereof, being carried in bearingssupplied by a .number of brackets 75 fastened to the lower angle bar 8.The` cross strip 71 be sides serving to clamp the lower margin of theinserted sheet against the platen, supplies a ledge for thevv lower edgeof the sheet Thus this bar is bent substantially at a right angleadjacent the lower edge of the platen as shown at 71al (Fig. 7 The upperen'ds of the steel straps 70 are hung upon laterally turned end portionsof crank arms 80v of a rock shaft 81 which is journaled in brackets 82fastenedto' the upper angle bar 7 (Fig. 2), three such brackets beinghere shown. Springs`83 coiled around this shaft between portions 'oftwoof said brackets tend to turn Jhe shaft in ay direction to throw thestrips 70 against the platen, and likewise the strip 71. Avhandle 84 isfastened to the shaft 81 and by forcing the same forward said springsmay be overcome and the bands 7 0 flexed and the strip 71 swung forward,as shown in Fig. 7. One' Y 9o of clamping one or more 'sli I tened tothe upper angle bar 7 4and having a 4extension passes the crown ofthelug, the. springs 83 snap the bands and the strip 71v to clampingposition, such as shown 1n struck-up portion 91 to engage a downwardextension 84aL of the handle. Thus when the handle is forced forward theend of this extension rides over the struck-u lug 91 and is caught andheld thereby vl)Fig.\7).` Said lug is sufficiently beveled on its rearend to permit the handle being forced back when the sheets are to beclamped uponthe platen. vAs soon as the endof the handle I also provi yvnected with the bands 70. Thus the latter are made with series ofperforations70b and ,the said cross strip 93 extends behind said bandsand carries short pins 93iL to engage said perforationsf Keepers intheform` of thin resilient plates 94 are fastened tothe f" "strip 93 and`'adapted to overlap the bands 'i 70 respectively, said keeper platesbeing per-- forated to engage said pins, as shown in Fig. 12. The stripcan thus be adjusted to engage over the upper margins of sheets ofvarying dimensions. As occasion may arise for running paper from a rollover the platen, I 'secure brackets 100 to the sidepieces 5' of thecradle and mount a pair of cross rods 101 in ears of these brackets andarrange a roll holder on these rods, said holder comprising a pair ofarms 102 with bosses to slide on the lower cross rod and bifurcatedupper'ends to embrace the upper rod. The previously mentioned brackets75 i -at vthe lowerkend of the platen are utilized Ito to support aguide for theroll paper B. Thus clips 110 fastened to said bracketscarry a partly tubular plate 112 under which there is a similar plate113 secured to and slightly spaced from the first plate and atthe' rearend bent back so as to form with the upper rear portion of the first,plate a flaring mouth into which the roll paper may be inserted. Thispaper then passes through the space between the plates and thence upover the platen and under the top crossV strip 93 which is preferablyformed with a serrated upper edge for use in severing the roll paper.

Rearward swinging of the platen and .cradlel is ,limited by abutment ofstuds 115 on the lugs' 5d vagainst the abrupt rear sides of notches 116ain slotted plates 116 pivoted to the carriage .brackets 4 and drawn downby spring ward the said studs occupy upper forward ends of theslots insaid plates and the latter are in' lowered position, as `shown in Figs.-1 and 4. Downwardly inclined cam. edges 116b define the upper sides ofthe forward portions of the slots and through engagement with the studsas enforced by de an upper crossl strip 93y (Fig. 12) arranged .to beadjustably con-4 s 117. When the platen is for-4 the springs 117 serveto offer resistance to f rearward swinging of the 'platen and cradle.

vThe wei lht o f the latter is considerable and l will or inarily`suiiice to hold the platen forward and this action coupled 4with the foverbalancing of the platen and parts which its being forced to suchposition by theoperator.

In. the present instance the lateral. position of the carriage isfrictionally maintained and. subject to indefinite variation within thelimits of shift from one extreme position to the other. Thus thetabulating rod 125, which extends between depending ears 4t of thecarriage end-pieces and is locked therein againstv any independent`.lateral movement, does not have secured to it the series of fingers ofthe (character shown in several of the above-mentioned prior patents,which fingers in those priorconstructions determine the columnarposition of the carriage, but the said rod in this kmove with it, willserve to throw the platen to printing position without the necessity ofinstance has africtional connection with a single finger 126,'whichfinger remains permanently interlocked with the notch of a fixed plate127 secured to a shortl skirt 3"b formed a't the middle of thetrack-casting (Figs. 4 4and 7). The rod is grooved lengthwise as shownat 1258L (Figs. 9-11) and the boss ofthe finger is similarly groovedl4`A key 130 engages these grooves and extends at its ends overthe ends ofsaid boss`(F. ig. 9). The rod may slide freely through the boss but.force applied to turn the rod will cause the key to bind in the groovesand create suilicient friction to. hold the carriage in position. `Acrank arm 125b on the right-y hand end of the said rod has a studengaging the bifurcated lower end of a pivoted arm or lever 140 (Fig. 1)which is heldforward by a stout spring 141, said spring thus applyingforce to turnthe rod 125 in such manner as to' create friction forholding 'the carriage in position in the manner just mentioned. The saidarm or lever is pivoted on'the same stud which supports the `righthandslotted plate 11G and said lever has a handle 1401 by which it can berocked to turn the rod 125 and relieve the friction when the carriage isto be shifted to a new position.

I employ a line-finder somewhat similar i to those heretofore used (seefor example said Patent No.V 922,547), this line-finder being in theform of a platel() Aextending from side to side of the machine properandapertured centrally, as shown 1n Fig. 3, for the projection throughl ofthe type 618 (Fig. l). vSaid line-finder plate is curved to conform withthe platen and lie closely adjacent the same-when it is in printingposition as illustrated lin Fig. 4, thus serving under these conditionstohold the sheet of paper smoothly over the platen4 around the printingline. Said plate is carried by a pair of side armsI 151 whlch arepivoted on brackets 152 .offthe machinek -lugs 156 on upstanding arms ofthe brackets 152, by the engagement of forward inclined end edges of the'detente 153 with the studs 155, as clearly shown in Fig. 7.

mVVhen the platen is rearward, as shown in Fig. 7, and it isdesired ltolocate the line of printing the said plate 150 will be forced rearwardto the dotted-line position shown in this figure of the drawing, thesprings 154 being overcome and the studs 155 seating in notches at themiddle portions of the detents 153 so that the plate will be detained inthe dotted-line position and the operator will not be required toforcibly hold it there. Theplate is marked, as illustrated in Fig. 3,for purposes of effecting verticall alinement in the printing.

A'guard plate 160 is arranged 'on the carriage so as to prevententanglement of the paper, in sheet-l or strip form, when the carriageis shifted back and forth, and also aid in guiding the paperover thelaten. This plate extends from side to side of the carriage andvertically from a oint just over the rod 125 to a point justV elow the'I line-finder plate 150 when the latter is forward or in `normalposition, so that these two plates arey virtually continuations of eachother. The lower plate 160 is curved like the upper plate and may beconveniently secured in position over the carriage rail andtrack-casting by lthin metal arms 160 extending through the open centerof the carriage rail and fastened thereto and to the plate.

A single inserted sheet may be printed upon at a time, or a stack ofsheets may be inserted, as shown in Fig. 7, and the uppermost or outersheet printed `upon and then removed by itself and the next lowermostsheet printed upon. When the platenis to be lowered, after the printingupon one .ehem has been' completed and a new sheet.

accomplished either by pressure applied directly upon the top ooperating the twirler knob 51.`

It will be seen that not only does the above- .described constructionserve the purpose of enabling relatively stiff sheetsl or cards to beinserted and removed and 'printed upon cleanly without involvingpronounced. bending or curling and so without affecting .thel

flatness for stacking'orfiling or temporary binding, but, aside fromthis', the sheets or cards can be inserted and removed 'with muchgreater facility and much more expeditiously for several reasons.' Forone. thing, no maneuvering by the operator to theplaten, or by r get thesheet square necessary for it will simply be`- dropped overthe face ofthe platen onto the ledge or shoulder 71a, the y platen being in.uppermost position and the clamping strip 71 thrownI forward. The meretripping of the handle 8,4 results in clampinV ofthe sheet inthiscorrect posi` tion. 'Ilis is of considerable importance because intabulatingf'upon vsheets of, this sort the same sheet isinserted andremoved many times, as for examplein 'bankvwork,

and of course it `should not vary in positionv one time from another,otherwise the tabulation would not be effected with entire acv curacy.Another advantage results from the absence of a friction feedsuch asthat inci- `dent to the running of paper between a` roller platen andressure rollers.` With such character of eed -it is Well nighvimpossibleA to eliminate all slippage and thereby insure absolutelyuniform spacingv and alinement, whereas with my. construction., this isinsured since the sheet is firmly clamped against the platen and thelinespacing involves no `friction feed of the paper at all. p This istrue with respect to thin as well as thick pa rand also whether thepaper is in sheet orm or in the form vof a strip drawn froma roll. Afurther ad vantage of the arrangement is that cards of quite smallsize,such as those used in ordinary card indexes, or even smaller cards,

can be successfully handled, Whereas with the ordinary rollerplatenfarrangement this is not at all practicable. `It will be noted inthis connection that the sheet need only be clamped at its lower edge asillustrated in Fig. 12 in which connection it is to be observed that thebands 70 are not called upon to engage the sheet but merely serve asconnections for operating the clamping strip or bar 71v and for carryingthe upper cross strip or bar 93 when thatl is employed. A rela-Y4 tivelystili sheet in the nature of a card may,

when dropped over` the face of the platen, assume an upright position ata tangentto the convex surface of the platen but when theplatter is swuforward the sheet orl card will be carrie againstthe plates 150 theplaten. As a mattei` of fact the operator willusually 'throw backv thefinder-plate 150 the next thing after inserting and `clamping thesheetor card, and the springs 151 added' to the weight of the plate andits arms, will lay the paper back over the platen andfthen act to smoothit down as the platen is lowered to adjust .the paper for the firstimprint.v Of course 'when the platen is then thrown forwardtheinder-plate yields and returns to its yfolded-upstate wherein italines with the lower guard plate 106, the two together keeping thepaper close against lthe platen throughout. In. thecasepf a ylongersheet than that illustrated in Fig. 12 or a thinner sheet it may befound desir.- able to employ the upper cross stripv or bar 93.
